Question

I purchase a replacement motor for a F5897-900 Hoover SteamVa Motor part # 43576197 or 27242051. The replacement motor has three electrical connectors + ground were as the orginal has two electrical connectors + ground. Do I ingnore the the thrid connector and hook up the wires to the same connectors as the orginal or do I have to do some rewiring.
